Bart inadvertantly moons an American flag. The Simpsons become outcasts in Springfield and the U.S. itself. They are imprisoned, only to escape and go to France. They then come back to America as part of "The one group that is always welcome in America" Immigrants without ID. It seems that this episode is satirizing the neo-patriotism that America went through in the wake of 9/11. But once again, it seems like another episode that is past its time as the sentiment shown in this episode is almost the complete opposite as what it is like today. A few funny things but I did not think it was all that great.
